Abstract
A thrombi removal device includes a shaft with a distal end and a proximal end and a helical coil attached at one end to the distal end of the shaft and extending in the distal direction from the shaft. The coil has a plurality of body portions with turns or winding spaced apart longitudinally and laterally to facilitate screwing the coil into the thrombus and to provide a sufficient open area into which the thrombus can be captured. The distal end of the coil is provided with a loop. The angle of the loop relative to a longitudinal axis extending through the helical coil is about the same as the angle of at least one body portion.
